Several media persons from television channels were hurt due to stone pelting. The rioters set fire to two party offices of the ruling party Communist Party of India (Marxist). The violence led to severe traffic snarls during the morning rush hour. Most of the violence was concentrated in the Muslim Majority neighbourhoods of Central and East Kolkata. Park Circus Area, Topsia, Tiljala, Tangra, Park Street- MullickBazar, Eliot Road, Ripon Street, Royd Street, Colin Street, Marquis Street, Raja Bazar, Sealdah, Moulali, C.I.T.Road and adjoining areas of John Burdon Sanderson Haldane Avenue (Park Circus Connector).

At 3 PM, four platoons of the army, each comprising 100 to 120 soldiers marched into the city from Fort William. 3 flag marches were conducted that evening.[3] Four more platoons were preparing to move soon.
